oil pressure light comes on at high speed

3 Answers

Too much oil in crank case at high speed would cause high oil pressure activating your oil pressure light, check your oil level. Could also be a faulty oil pressure sensor works fine at idle speeds but once oil pressure builds up it may stop working, there are two sensors usually on the vdubs low and high pressure change both of them their are cheap to buy and easy to replace.

My 2003 Jetta has had both sensors replaced but the oil light is still blinking (only at
times) at either 1600 RPM or 1800 RPM when I am in a high gear and gassing the car
and passing 1600/1800 RPM ...
